Closing and clamping lever for a ski boot

Abstract

The closing and clamping lever for a ski boot comprises a substantially perimetral structural casing (10a,12a,13a) which is provided on at least the sides of the body (10b,12b,13b) of its components, which is made of plastic. A couple of transverse portions (27,28) are also provided. The casing is for example made of metal or an engineering polymer. In this latter case it may be manufactured integrally with the body (10b,12b,13b) of the lever components.

It is claimed: 
     
       1. In a closing and clamping lever for a ski boot having an operating arm, an articulating arm and a fastening arm which cooperate to close a flap on a ski boot and which arms have a body portion made of plastic, the improvement comprising a structural casing composed of walls fixed onto outward sides of the body portion and the walls cover partially upper and lower edges of the outward sides of the body portion, which upper lower edges are transverse relative to the walls, said casing being made of metallic material or a polymer. 
     
     
       2. Closing and clamping lever according to claim 1, wherein said walls are made of a metallic material. 
     
     
       3. Closing and clamping lever according to claim 1, wherein the body portion has a cross-sectional shape essentially in the form of a U. 
     
     
       4. Closing and clamping lever according to claim 1, wherein said structural casing is made of a polymer. 
     
     
       5. Closing and clamping lever according to claim 1, wherein the structural casing has at least one transverse portion. 
     
     
       6. In a closing and clamping lever for a ski boot having an operating arm, an articulating arm and a fastening arm which cooperate to close a flap on a ski boot and which arms have a body portion made of plastic, the improvement comprising a structural casing composed of walls fixed onto outward sides of the body portion and upper and lower edges of said walls are transverse relative to the walls and are covered by corresponding edges of the outward sides of the body portion, said casing being made of metallic material or a polymer. 
     
     
       7. Closing and clamping lever according to claim 1, wherein the body portion has a cross-sectional shape essentially in the form of a double T. 
     
     
       8. Closing and clamping lever according to claim 6, wherein said walls are made of a metallic material. 
     
     
       9. Closing and clamping lever according to claim 6, wherein said structural casing is made of a polymer.
